What are the main items included in battery testing?

Battery testing typically involves several main items, including:

1. Battery capacity test: This test aims to determine the actual capacity of the battery, that is, the amount of electricity it can store. Measure the capacity of the battery through charge discharge cycle testing or using specific instruments, and ensure that it matches the capacity specified by the manufacturer.

2. Battery cycle life test: This test aims to simulate the cyclic charging and discharging process of the battery in actual use, in order to evaluate the battery's lifespan and stability. Perform cyclic testing through repeated charging and discharging, and monitor the degradation of battery performance.

3. Battery safety testing: This test aims to evaluate the safety performance of the battery under extreme conditions, including overcharging, overdischarging, high temperature, short circuit, and other situations. By simulating various extreme conditions for testing, ensure that the battery operates within a safe range.

Vehicle testing technology typically includes the following aspects:

-Charge and discharge management system: By monitoring the charging and discharging process of the battery, adjusting the current and voltage, effective management of the battery is achieved, ensuring the safety and reliability of the charging process.

-Temperature management system: By monitoring and controlling the battery temperature, it avoids the impact of high or low temperature on battery performance and ensures that the battery operates within a suitable temperature range.

-Battery cell balance system: used to monitor and regulate the charge and discharge status of different cells in the battery, ensuring the balance of the state of each battery cell and extending the battery life.
